Calculate, visualize, utilize.

Easy operation, precise modeling.

The intuitive interface hides powerful options. Access data directly as typical meteorological year (TMY) and actual meteorological year (AMY). Model tilted radiation (plane of array) and diffuse radiation, get results in minute time resolution, use different clear sky options. Integrate future scenarios and extreme years for robust risk assessment and long-term planning.

Integrate Climate data.

Thanks to various output formats, Meteonorm data can be seamlessly integrated into other tools. Meteonorm provides industry specific formats: CSV, JSON, EPW, PVSyst, TMY3, Wufi/WAC.

Intuitive location setup.

Benefit from location-based features. Altitude, albedo, turbidity, and horizon data are set automatically (or by you). Focus on your project, not configuration details.

At a glance.

Meteo data and models

Meteorological data TMY (typical) and AMY (actual), models for tilted radiation (plane of array), diffuse radiation, minute time resolution, clear sky options (esra and solis).

Climate Change

Future climate scenarios. Low, medium and high emission pathways SSP1-2.6, SSP2-4.5 and SSP3-7.0 from IPCC AR6.

Extremes (Soon)

Simulation of irradiance and temperature extreme scenarios. For robust risk assessment.

Location

Define your location with parameters such as coordinates, altitude, albedo, panel orientation, situation, horizon and turbidity.

Preview

Shows the resulting monthly solar data and daily temperature data in charts for quick evaluation. Summarized in a table with monthly values.

Powered by Climate API

The web application relies on the climate API, ensuring it uses precisely the same algorithms, data, and parameters.

File Formats

Export to industry-specific file formats (CSV, JSON, EPW, PVSyst, TMY3, Wufi/WAC).

Intuitive layout, effortless results.
